Vitax Hydrangea Colourant - 250g
Vitax Hydrangea Colourant is ideal for changing pink hydrangeas to blue. This colourant releases iron and aluminium salts into the soil which depending on the variety will turn pale pink hydrangeas blue and darker pink hydrangeas blue or mauve.
- For use on both pot grown hydrangeas and those grown outdoors
- Readily dissolved in hot water
- Mix with soil for best results
- Best results are obtained with plants growing in acid soil; when using on alkaline soil the proportions should be doubled
